Samsung Galaxy S III Ultrafast â€“ available now on Three.

Inspired by nature and designed for humans, this beautifully crafted phone has a large 4.8-inch, HD Super AMOLED display which fits more of the content people love on one screen.

It comes in Marble White and Pebble Blue, is loaded with smart features and even knows when youâ€™re looking at it so the screen doesnâ€™t turn off. By vibrating, the Galaxy S III Ultrafast lets you know when you have missed a message or call, and you can call your friends by simply moving the phone towards your ear. A simple voice command is enough to wake the phone from the lock screen.

Boasting a quad-core processor, it comes with a large battery capacity to match so thereâ€™s less worry about the device unexpectedly powering down while enjoying HD clips on your commute home. The intuitive smartphone also includes an 8 megapixel camera with auto-focus and LED flash as well as a 1.9 megapixel front camera for video calls with friends and family.
